Why notebook no sound

From that same Sound menu, select the audio device you're trying to use, click Properties, and poke around the options that appear. Make sure the right supported formats are checked, any enhancements are disabled, and that Exclusive Mode is unchecked in the Advanced Tab.

You might even try turning off any Spatial Sound enhancements as well. Try playing audio again, and see if any of those options were the cause of your troubles. In rare instances, a hardware incompatibility, software update, or Windows reinstallation can cause your sound to stop working, and you may need to tweak something in the BIOS.

First, make sure your sound card is enabled in the BIOS, as it could have gotten disabled at some point. If your manufacturer has released a new version recently, it might be worth updating. Just be sure to read the instructions and proceed carefully, as a BIOS update can also break things if done improperly. When in doubt, if a piece of PC hardware isn't working, check the drivers. Click the Start Menu and type "device manager," pressing Enter when the option appears.

Scroll down to Sound, Video and Game Controllers and expand the menu to show all the possible audio output devices in your PC. If there's a yellow exclamation mark next to any of these, that's a sign you may need to find and install its driver from the manufacturer's website.

If not, installing the driver is worth a shot anyway. You can also try uninstalling the driver: right-click the one you're trying to use—in my case, my laptop uses Realtek Audio—and choose Uninstall Device.

To quit the coreaudiod process, you can open Activity Monitor , type coreaudiod in the search box and click Force Quit. Alternatively, launch Terminal and type sudo killall coreaudiod command. Press Return , enter your password and check if the audio works again. In this case, shut down your Mac and restart it.

This will start the daemon and reinitialize the coreaudiod process. Third-party app and plugin issues integrating with your Mac may affect the audio owing to hardware and software incompatibility, especially when a new macOS is released.

To manage and deal with the audio not working on your laptop for specific apps on your Mac, use the following steps:. Each time a new macOS is released, it not only comes with improvements and new features, but also changes in audio drivers, kernel frameworks, Unix tools, new bugs and sometimes audio issues follow.

Apple also improves and fixes audio latency, reliability of USB audio issues and other related user concerns. If you find audio not working on your Mac laptop, try updating your operating system to the latest version and see if it fixes the audio issue. Your Mac laptop uses nonvolatile random-access memory to store different settings such as sound volume, time zone, display resolution and recent kernel panic information among others, and access them quickly.

Reset it to clear any glitches with any of these and other attributes. To do this, shut down your Mac and power it on again. Immediately press and hold Option, Command, P and R keys for about 20 seconds and release them when you hear a startup sound.

If you have a Mac with the Apple T2 Security Chip , release the keys after the Apple logo appears and disappears again. Turn off the firmware password if your Mac has one, and then open System Preferences when your Mac finishes starting up. Adjust any settings like sound volume and others that were reset.
